Offshore wind power can produce a lot of energy

At sea, the wind sometimes blows stronger than on land.
Offshore wind turbines can also be larger and stronger than those on land, creating a lot of electricity.

Offshore wind power is low-polluting

Offshore wind produces little CO2.

Offshore wind power is ideal for France

France has large and numerous maritime areas, which is ideal for offshore wind power.

Offshore wind power creates jobs

To build an offshore wind farm, you need engineers, technicians and specialized workers.

Everything starts from the wind which turns the blades

The blades always face the wind. The wind turns the blades which are attached to a single part called a hub.

Electricity is transported using underwater cables

Electricity is carried by a cable located underground which goes to a station which then distributes this electricity to your house.

The blades drive a generator

Thanks to the sea winds, the blades drive the generator, which produces electricity.

Electricity reaches the earth

Electricity is carried by an underwater evacuation cable to a landfall junction and then to the connecting electrical substation, before powering your home.
